TYPE-WRITING MACHINEL Patented May 14,1907.

A li ati fil d December 28,1906.- Serial No. 849,171.

T at whom' it may concern.-

Be it known that I, WILLIAM F. IIEL OND, a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connection t; have invented certain @new and useful Improvements in Typeriting Machines, of which the following .18 a

specification. y

This invention relates to stops for limiting re the travel of carriages ofitypewriting machines and particularly to th'e'stops which regulate the the page of writin In the .well known Underwood typewrit-ing' I 5 machine, the adjustable stop upon the framework which limits the return movement of the carriage to begin a new line, has a range of adjustment wh ch is only about half the 'rangeof travel of the carriage, and it is one '20 of the objects of my invention to effect a,suh

stantial increase in the Width of the left hand margin on the sheet obtainable on said machine. To this end, I provide upon the carriage, inaddition to the usual stop, an aux 2 5 iliary stop which can be brought into use at will, to engage the margin stop upon the machine fraine at a point considerabl y in advance of tne usual stop upon the carriage,

' whereby the range' of travel of the carriage 0 is greatly reduced and a correspondingly greater left hand margin obtained upon the sheet. I Iprovide means for mechanically detaining the' auxiliary stop 1n either effective or ineffective position at will, so that it may 35 be thrown out of use when not needed. Both stops uponthe carriage arereleasable by a single release key, and both are constructed to ride freely over the framework stop during the run of the carriage in letter feeding di- 0 rection. I y

Other features and advantageswi-ll hereinafter appear, and it will be understood that the improvementsare adapted for other pur-f 5 bodied in many different forms.

In the accompanying drawings, Figure 1 is a perspective view of the upper front part of an Underwood? typewriting machine, showing the carriage arrested by the HILIXII'."

. In said'rnachine, type-barsl strike against the front side of a platen 2, Fig. 5, the latter mounted upon a carriage 3 connected by a strap 4 to a spring-barrel *5 which pulls the carnage in letter feeding direction; the carriage having aroll 6 to run upon a rail 7. Upon the rail7 is usually provided a rack 8 e'ngageab'leby .a tooth 9 provided in a carrier 10 mounted partly 12, which is in the path of the stop 13 upon The carrier 10 is releasable by justedin the direction of the travel of the carriage; but its'range ofadjustn ent islimi'ted by collars '15 which the sheet is'somewhat restricted. A pointer or an index 16 upon the stop carrier 10 cooperates with a scale 17 upon the framework upon the rod 7 and partly- .upon a front rod 11 and having a margin stop supportthe rod 11, so that the width of the left hand margin on to guide the operator in setting the margin stop. An index 18 upon the-carriage cooperates the same scale to indicate the progress of the carriage. 1

The stop 13 is mounted upon an arm 19 pivoted at 20 upon the front bar of the carriage, and from said pivoted arm 20 extends to the extreme right hand end of the carriage, and carries at its end a release key 21, whereby the stop 13'1nay be lifted clear of the mar-- 'gin stop 12, Fig. 3; the arms 19, 20-forming a lever of the first order. "As so far de; scribed the parts are in. common'use u'pon' I provide upon the carriage an auxiliary stop 22, to engage'said margin stop 12 at a point two or three inches in advance of the usual stop 13, thereby increasing to that extent the width of left hand-margin obtain-y able u on the sheet. '2' Said stop 2-2 is formed up on t eright hand end of an j at 24:.upon the arm19 between the pivot20 and the stop 13.; Aspriigtig 25 fixed by a screw. bears -at its free end'np'i 26 upon the arm 23- v against. a ledge 27 formed upon the'carriage bar, and. presses downfconstantly both arms- 23 and 19,--s o asto hold bo'thfstops 22 and-13 ineflective positions.

Bream. 'of'a h ndle 28 pivoted -at.'29 upon, an arm; 30:.extendiner' arm 2-3 pivoted loo to-theyleft from the-pivdti24, thestops; 2 2 1v i may be rendered either effective or ineffec provided upon tive at will; a cam 31 being I said finger-piece 28 to engage the under slde of the carnagelledge 27 ,to press and hold down the'arm and elevate the arm 23' and stop 22 above the margin stop, Fig- 4; the

' arms 30 and 23forming a leverv of the first 1 the other way Fig.2, the cam 31 is engage order. When the finger-piece 28 is swun I release and the lever 30, turned by the spring 25 until the stop 22 is depressed sufficiently to the marginxstop 12;. the turning movement of'said lever being limited bya' shoulder 32 formed upon the handle 28 to bear against the ledge 27. The right hand I end of the arm 19 is normally pressed by the spring 25 up against the underside of said ledge 27 as at 20*, Fig."2. 'A' stop 33 limits the lay of the handle 28.

tion, the stop 22 is out of use, but when it is swung to the osition seen at Figs. 1, 2 and 3, the stop 22 is in use and engages the mar gin stop'12 to. reduce the'range of. travel of the carriage and increase the left hand margin on the sheet. The distance between the stops 22 and 13 maybe equal to two or three of the major divisions 34 on the scale 17 so that the operator may readily set the index 16 to the pointrequire d for the extra wide margin. it isdesired at any time to write in such'wide margin, it is only necessary to press the key 21-, Fig. 3,,whereby the pivot 24 is carried up and the arm23 is swung up about the point of contact of the shoulder 32 with'the ledge 27, so that the stop 22 clears the margin stop 12. It will be understood that the operator may thereupon eitherhold the release key down-until ,the

carriage has been moved ,to the extreme right, or may permit said release key to rise so that the stop'13 may engage the margin stop 12, thereby mechanically determimng out as illustrated,

I a submargmal' point for beginning the line of 22* may be provided to prevent the-stop'22 from sliding down along theface 12 the stopsengage each other.

Having thus described my invention, I claim: I
